Zinachitika kuti kulikonse komwe kuli zochitika za anthu, zinyalala ziyenera kuwonekera. Ngakhale malo sanali osiyana. Munthu atangoyambitsa magalimoto oyendetsa dziko lapansi, vuto lazinyalala zam'mlengalenga zidayamba, zomwe zikuwonjezeka chaka chilichonse.
Kodi zinyalala zamlengalenga ndi chiyani?
Zinyalala zamlengalenga zikutanthauza zinthu zonse zopangidwa ndi munthu ndipo zimapezeka pafupi ndi danga lapansi, osachita chilichonse. Kunena zowona, awa ndi ndege zomwe zatsiriza ntchito yawo, kapena zalephera kugwira bwino ntchito zomwe zimawalepheretsa kupitiliza ntchito zomwe adakonzekera.
Kuwonjezera pa nyumba zonse, mwachitsanzo, ma satellites, palinso zidutswa za matumba, mbali za injini, zinthu zosiyana. Malinga ndi magwero osiyanasiyana, m'malo osiyanasiyana ozungulira dziko lapansi, zinthu zopitilira mazana atatu mpaka zana zikupezeka nthawi zonse, zomwe zimawerengedwa ngati zinyalala zam'mlengalenga.
Chifukwa chiyani zinyalala zam'mlengalenga ndizowopsa?
Kukhalapo kwa zinthu zopangika zosalamulirika mu danga lapafupi ndi dziko lapansi kumabweretsa chiopsezo pakugwiritsa ntchito ma satelayiti ndi ndege zamlengalenga. Chiwopsezo chimakhala chachikulu anthu akakwera. International Space Station ndi chitsanzo chabwino cha ndege zomwe sizikhalaponso. Kuyenda mwachangu kwambiri, ngakhale zinyalala zazing'ono zitha kuwononga kukhathamiritsa, kuwongolera kapena magetsi.
Vuto la zinyalala zam'mlengalenga ndizobisalanso poti kupezeka kwake mozungulira padziko lapansi kukukulirakulira, komanso pamlingo waukulu. M'kupita kwanthawi, izi zimatha kubweretsa kusatheka kwa ndege zapamtunda konse. Ndiye kuti, kachulukidwe kazomwe zimafotokozedwa mozungulira ndi zinyalala zopanda ntchito zikhala zazikulu kwambiri kotero kuti sizingatheke kunyamula ndegeyo kudzera mu "chophimba" ichi.
Kodi chikuchitika ndi chiyani kuti ayeretse zinyalala zam'mlengalenga?
Ngakhale kuti kufufuzidwa kwamlengalenga kwakhala kukuchitika kwa zaka zopitilira theka, lero palibe ukadaulo umodzi wogwira ntchito pazochepetsa zinyalala zam'mlengalenga. Kunena zoona, aliyense amamvetsa kuopsa kwake, koma palibe amene akudziwa momwe angathetsere vutoli. Nthawi zosiyanasiyana, akatswiri ochokera kumayiko otsogola omwe akufufuza zakuthambo apanga njira zosiyanasiyana zowonongera zinyalala. Nawa otchuka kwambiri:
- Kupanga zombo "zotsuka". Monga momwe anakonzera, ndege yapadera imayandikira chinthu chomwe chikuyenda, kunyamula ndikunyamula pansi. Njira imeneyi kulibe.
- Satellite yokhala ndi laser. Lingaliro ndikukhazikitsa satelayiti yokhala ndi makina amphamvu a laser. Pogwiritsa ntchito mtanda wa laser, zinyalala ziyenera kusanduka nthunzi kapena kuchepa kukula.
- Kuchotsa zinyalala mumsewu. Mothandizidwa ndi laser yemweyo, zinyalalazo zidakonzedwa kuti zichotsedwe mumsewu wawo ndikuziwulutsira m'malo olimba amlengalenga. Zigawo zazing'ono ziyenera kuwotcha kwathunthu zisanafike padziko lapansi.
